This invention relates to refrigerators and more particularly to a refrigerator or ice box using cool air as a refrigerating medium.

An object of this invention is to provide an exceedingly simple refrigerating or cooling means which is cooled by coldv air drawn from the basement or cellar of a house. i

Another object of this invention is to pro:

vide in a cooling means or refrigerator of this kind means for forcibly drawing the cool air through the cooling means so that the interior of the box will be maintained in the desired cool condition.

The above and various other objects and 15. advantages of this invention will in part be described in and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated inthe accompanying drawa ing wherein Figure 1 is a detail side elevation of a de vice constructed according tot-he preferred embodiment of this invention partly broken away and partly in section.

Figure 2 is a vertical section taken on the line 22 of Figure 1.

Referring to the drawing wherein like numerals of reference designate corresponding parts throughout the several views, the

numeral 10 designates generally a box of insulated construction which has a door 11 at the front end thereof, and is provided at the bottom with supporting legs 13. The interior of the box 11 is provided with a plurality of shelves 12 upon which the food articles may be placed. 7

In order to cool the interior of the box 10, I have provided a lower manifold 14 and an upper manifold 15 which are connected together by means of a plurality of cooling pipes 16. These pipes 16 are disposed in parallel relation to each other and are of .suitable size and thickness so that -the cool air passing therethrough will cool the exterior of the pipes or tubes 16 and thereby cool the interior of the box 10.

The lower manifold 14 is provided with a nipple 17 which extends through the bottom of the box 10 and a conduit 18 is connected to thisnipple and is extended to the base- 1932. Serial No. 610,468.

ment or other normally cool place from which .the cool air is drawn through the conduit 18 and passedthrough the tubes 16. The upper manifold 15 has a nipple 19 connected thereto and extending through the top of the, box 10, and a pipe 20 is connected at one end to the nipple 19 and the other end thereof may be connected to a suitable draft producing means such as a chimney fine or the like.

' In order to assist the movement of air 69 through the cooling tubes 16, I have provided a fan F which has the blades 21 thereof disposed in the pipe 20 and the operation of this fan F will suck the cool air throuwh the 'tubes 16 and force this air out through the 55 outlet pipe 22.

While I have shown a fan connected to the outlet pipe 22,1 do not wish to be limited to this particular construction as any other means of producing'a draft may be used such as alight bulb or other means for producing heat within this outlet pipe, so as to cause the heated air to rise in this pipe and the draft created thereby will draw the cool air through the intake pipe.

In the useand operation of this device, the box 10 may be placed at the desired point and the intake pipe 18 connected to the nipple 17 and open to the atmosphere in the opposite end, this opposite end being disposed at arelatively cool place in the cellar or basement of the building, from which point the cool air is drawn through the cooling tubes 16 by the fan F. In many cases, it will not be necessary to use either, the fan F shown or means for producing a draft so as to draw the cool air through the cooling pipes 16, but where such draft producing is necessary, the fan or other draft producing means may be operated and the cool air will be drawn through the cooling tubes and forced out through the outlet pipe 22. s

It is, of course, understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.

What is claimed is: h

1. A refrigerator comprising an insulated box, an upper manifold within the box, a lower manifold in the box, a plurality of cooling pipes connected to the manifold and disposed in parallel relation to each other, and a nipple carried .by each manifold and extending through the adjacent wall-of the box.

2. A refrigerator comprising an insulated box, an upper and a lower manifold in the box, a plurality of parallel cooling pipes mounted within the box and connected to said manifolds, nipples carried by each manifold and extending through the box, an intake pipe connected to one of said nipples and having the opposite end thereof disposed in a position to receive cool air, and means connected to the other nipple to draw the cool air through said intake pipe and said cooling pipes.

3. A refrigerator comprising an insulated box, an upper and a lower manifold inthe box, a plurality of cooling pipes connected to the manifolds, nipples carried by each manifold and extending through the box, an intake pipe connected to the lower manifold, an outlet pipe connected to the upper manifold, and means disposed within the outlet pipe to draw the air. through said intake pipe.

4. A refrigerator comprising an insulated box, an upper and a lower manifold in the box, cooling pipes connected to the manifold,

nipples carried by eachmanifoldand,extending through the box, an intake pipe connected at one end to the lower nipple, an outlet pipe 7 connected to the upper nipple, a fan mounted on the box and having the blades thereof disposed within the outlet pipe whereby to draw the cool air throughthe intake pipe and the cooling pipes.

In testimony whereof I hereunto affix my signature.

- JOSEPH LONG.
